ROLLING-MILL FOR MANUFACTURE OR SHAPING OF CHAINS.

SPECIFICATION forming part of Letters Patent No. 537,781, dated April 16, 1895.

Application filed April 12, 1894- Serial No. 507,267- (No model.) Patented in Luxemburg August 10, 1893, No. 1,874; in France August 11, 1893, No. 232,182,- in England August 12,1893,No. 15,403; in Norway August 16, 1893,1210. 3,391; in Belgium August 18, 1893, No. 106,021 and in Italy September 30,1898, LXVIII, 83.

To aZZ whom it may concern: Be it known that I, OTTO KLATTE, a subjec of the King of Prussia, residing at Neu wied-onthe-Rhine, Germany, have invented certain new and useful Improvements in Rolling-Mills for the Manufacture 0r Shaping of Chains, of which the following is a specification.

My invention has reference to those rolling mills which have four rolls arranged in two pairs at right angles to each other, the peripheries of which have grooves for the manufacture of smooth bars or are provided with cavities and protuberances'in such a manner, that on smooth bars corresponding impressions will be produced and for instance an X shaped bar will be transformed into the shape of a series of connected chain links, or the roughly formed links of a chain will be compressed into the desired finished shape.

Foreign patents have been granted for this invention as follows: in France, No. 232,132, dated August 11, 1893; in Belgium, No. 106,021, dated August 18, 1893; in Italy, No. LXVIII, 88, dated September 30, 1893; in Norway, No.

3,391, dated August 16, 1893; in Luxemburg,

No. 1,874, dated August 10, 1893, and in Great Britain, No.15,403, dated August 12, 1893.

The subject of the present invention relates to arrangements for adjusting the rolls in such machines in the horizontal and vertical planes and for preventing the jumping of the rolls. A mill provided with such arrangements is represented in the accompanying drawings, in which- Figure 1 is a front view partly in section; Fig. 2, a plan of the mill, and the left half of Fig. 3 is a section on the line 19-20, Fig. 1, looking from left to right, while the right hand half of Fig. 3 represents a section on the line 21-22 of Fig. 1 likewise looking from left to right.

The shaft 21 of each of the four rolls is supported in a bearing at each end in order to prevent the bending or deflection of the same. The two bearings of the vertical shaft of each horizontal roll form a continuous yoke piece 22. Each of these double bearings is transversely movable on horizontal guides 47 'which are attached to standards 23. This movement is effected byadjusting the lateral wedges 24, Fig. 3, (right hand,) which bear on one side against the bearings 22 and on the other side against shoulders 48 of the stand ards 23. To each of these wedges a bolt- 49 is attached, which passes upward and through a lug 50' on the standard 23 and is provided both above and below this log with a nut.

The guides 47 of each forked hearing are at tached to a plate 51, Fig.1 (right hand) and this plate has two vertical guides 52 on the oppositeside, Figs.- 1 and 2 (left hand), which are movable in vertical grooves in the standard 23. This plate 5i rests at the bottom on two wedges 25, Figs. 1 and 3, of which only one can be seen in the drawings. The one wedge is situated under the one and the other wedge under the other end of the plate 51, and each wedge rests-on a lug 53 of the stand ard 23. The wedge, which is not drawn, has a bolt 54 which passes througha hole in the wedge shown and on the farther side of the same carries a collar 55 and a nut 56. When this nut is tightened the two wedges 25 approach one another and thereby raise the plate 51 and with it the forked bearing 22 and the shaft carried in the same. For facilitatingthe vertical adjustment each forked hearing 22 is connected to a strap 26, which hangs from the cross girder 27 connecting the two standards 23 at the top and by turning the adjusting screw 28, which passes through the strap, the forked bearing can be either raised orlowered. The strap 26 is at the bottom at 29 detachably connected to the bearing 22 in order that the latter can be sufficiently displaced to allow of the changing of the rolls. When the bearings 22 have been properly adjusted they are securely bolted to the standards 23 by the bolts 30, Fig. 1 left hand. i

The two bearings of the upper roll form a part of the cross girder 27, which is adjustable in the vertical direction by means of the regulating screws 31, Fig. 1' top, which rest with their bottom ends on the standards 23.

The

possible to the vertical middle plane 19-20 Fig. 1 of the frame of the machine and to the Vertical middle plane at right angles thereto, so as to reduce the deflections of the cross girder, and thereby the jumping of the upper roll, to a minimum.

A to and fro movement of the cross girder 27 is prevented by the tongues 33 on the heads of the standards 23 Figs. 1 and 2 right hand, which fit in corresponding grooves 34: in the cross girder, and further bymeans of the lateral bolts 35 passing through the headsof the standards and vertical slots 36 in the cross girder.

I have already explained that the two'horizontal rolls are adjustable verticallyandhonizontally in a plane parallel to the plane of the standards. These standards 23 are made movable on the bed plate in order that the horizontal rolls may also be adjusted in a plane perpendicular to that of the standards and to :permit of the substitution of smaller or larger rolls. Whenthe standards arethns moved the stays 37 connecting them mustof course be correspondingly adjusted. These stays 37 as well as supporting the standards also prevent the springing of the=horizontal rolls. The bearings of the lower rollare also movable on the bed plate to insure accurate adjustment Fig. 3.

The driving shaft 38, which is detachably connected with the shaftof theupper rolLFig. 1 left, is adjusted bymeans ofthe screw coupling 39 and the regulating screw 40,.and the intermediate shaft 41, which is likewisedetachably connected with the shaft ofthe lower roll, is adjusted by the wedge 42. The shaft 38 drives the intermediate shaft 41 and the lower roll by means of the g aring 43, 44:.

The motion communicated directly to the upper roll by the driving shaft 38 is trans-'- mitted to the bevel wheels 46 on the horizontal rolls by the bevel wheels 45 011 each side of the upper roll. Various sizes of gear and bevel wheels are provided to correspond to the differentdiameters of the various rolls.

The method of driving the rolls described above is 'principallysuitable for therollingof large chains. For smaller chains or for the pressing in of smaller cavities the power required is not sogreat and therefore it is not necessary to drive the lower roll by means of gearing. Instead of the gearing, both sides of the lower roll and the under sides of the horizontal rolls are provided with be-velwheels which engage in one anothersimilarly to the bevel wheels 45 and 46. This arrangement canalso be used in combination with the 'intermediateshaft.
